Question

When the woman came back home, she had no idea how it ____ that her husband met with trouble again.

A．came about

B．came out

C．came up

D．came across

Answer 1

A

come about“發(fā)生”常與how連用，題中it是形式主語(yǔ)，后面的that從句是真正的主語(yǔ)。另外，come out出現(xiàn)、出版、(消息)傳開(kāi)、沖洗、罷工、(顏色或污點(diǎn))被洗去、結(jié)果是(right/wrong)；come up走過(guò)來(lái)、出現(xiàn)、發(fā)生、被提出、(彩票)中獎(jiǎng)、(太陽(yáng))升起；come across偶然遇見(jiàn)、無(wú)意中發(fā)現(xiàn)。
